In a TTL IC environment logic ‘0’ is represented by a voltage 0 to 0.7 Volt direct current (DC, Direct Current), whereas the logic ‘1’ is represented by DC voltages as high as 3.5 to 5 Volts.<\/span>

In a digital IC, an electronic point in the form of a cable or leg IC, will manifest one of two logical states, ie logic ‘0’ (zero, low) or logic ‘1’ (one, high).<\/span> An electronic point represents a ‘binary digit’ or commonly referred to as ‘bit’.<\/span> Binary means the number system ‘two-an’, that is, numbers that only recognize two numbers, 0 and 1.<\/span><\/p>\n

1 Microprocessor<\/b><\/span>
\n Microprocessor is a data processing device that is the development of Integrated Circuit (IC) technology. There are several terminology used to show the density of an IC chip, Small Scale Integration (SSI packing several tens of transistors), Medium Scale Integration (MSI – packing up to several hundred transistors), and now the developing one is Very Large Scale Integration (VLSI packs tens of thousands to millions of transistors).<\/span><\/p>\n

Ultra-Large Scale Integration (ULSI) increases that number to millions.<\/span> The ability to install so many components in a chip that measures half a coin pushes down the price and size of the computer.<\/span> It also increases the workability, efficiency and reliability of the computer .<\/a><\/span> The Intel 4004 chip created in 1971 brought progress to the IC by putting all components of a computer (central processing unit, memory, and input \/ output control) in a very small chip.<\/span><\/p>\n

Previously, ICs were made to do a specific specific task. Now, a microprocessor can be manufactured and then programmed to meet all the desired needs.<\/span> Not long after, every home appliance like microwave oven, television, and car with electronic fuel injection equipped with microprocessor.<\/span><\/p>\n

Examples of ULSI technology, such as the 8086 microprocessor containing 40,000 transistors, 80286 consisting of 150,000 transistors, 80386 loading 250,000 transistors, 80486 has 1.2 million transistors, 80586 (Pentium) 3 million transistors more while the Intel Core 2 Duo has 271 million Transistors and Intel Quad Core 2 Extreme consisting of four processor cores.<\/span> Further development of 80 core microprocessor.<\/span> Please calculate your own transistor content and it will develop continuously.<\/span><\/p>\n
